Allow future control toolbar to be hidden (default) or shown.

 Even if no control toolbar is implemented for ActiveX yet, we already
 provide the code to enable/disable it for compatibility with Firefox
 API behaviour.
 The getter used to know if toolbar is shown will always return FALSE
 until a toolbar is implemented. (getter which will be available soon
 for Firefox)

To use it:
- ActiveX global property named "toolbar":
   For HTML : <param name="toolbar" value="True" />

- API on IVLCControl2 interface, property "toolbar" (RW):
   For Javascript : yourvlcobject.toolbar = false;
                    isToolBarShown = yourvlcobject.toolbar;
